Adding Exercise to Antidepressant Medication Treatment for Depression (TREAD)

September 1, 2020 updated by: Madhukar H. Trivedi, MD, University of Texas Southwestern Medical Center

Treatment With Exercise Augmentation for Depression (TREAD)

This study will assess the effectiveness of an exercise program in improving antidepressant medication treatment for individuals with major depressive disorder (MDD).

Study Overview

Status

Conditions

Detailed Description

Partial response to antidepressant treatment is common in people with MDD and is associated with significant morbidity and reduced quality of life. Pharmacological therapies have been used to augment the effect of antidepressants; however, such therapies are associated with a range of adverse effects. Studies indicate that exercise may be safe and effective in augmenting depression treatment. This study will determine whether exercise can complement selective serotonin reuptake inhibitor (SSRI) therapy in people with MDD who have residual symptoms of depression despite drug treatment.

Participants will be randomly assigned to either high frequency exercise or low frequency exercise for 12 weeks. Depression symptoms will be measured weekly. Quality of life and satisfaction with the study will also be measured. Depression scales and self-reports will be used to assess participants.

  • Interventional Model: PARALLEL
  • Masking: SINGLE

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
EXPERIMENTAL: SSRI+ LD
A low dose aerobic exercise (LD) augmentation intervention to SSRI
Eligible participants who have completed an adequate trial of SSRI monotherapy and all screening visits are randomly assigned to 24 weeks of SSRI augmentation with : a low dose of aerobic exercise (LD) or a public health dose of aerobic exercise (PHD). The acute phase of TREAD consists of the first 12 weeks of exercise augmentation intervention and includes: a) an individualized PHD- or LD aerobic exercise prescription; b) an empiricallybased behavioral intervention, including selfmonitoring tools and an interactive website, designed to maximize exercise adherence and minimize drop-out; and c) exercise instruction and supervised training sessions at The Cooper Institute (CI) as well as self-administered, home-based training sessions.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Remission (Score of 12 or Less on Inventory for Depressive Symptomatology- Clinician-rated)
Time Frame: 12 weeks
The primary outcome measure- percentage of participants with remission (score of 12 or less on Inventory for Depressive Symptomatology- Clinician-rated). The change over time in probability of remission (IDS-C30 score ≤ 12) was compared between groups using a generalized linear mixed model (GLMM)41 as implemented in SAS (Proc Glimmix; SAS Institute Inc, Cary, North Carolina).
